Metro Ethernet Definition could be the use of Carrier Ethernet engineering in metropolitan location networks (MANs). Since it is typically a collective endeavor with several financial contributors, Metro Ethernet offers cost-effectiveness, reliability, scalability and bandwidth management superior to most proprietary networks.

s) and specific end customers to a extensive place network (WAN) or towards the World wide web. Businesses, academic institutions and government companies in huge cities can use Metro Ethernet to connect branch campuses or offices to an intranet. A normal Metro Ethernet system includes a star network or mesh network topology with individual routers or servers interconnected by means of cable or fiber optic media.

"Pure" Ethernet technologies while in the Man setting is reasonably inexpensive in comparison with Synchronous Digital Hierarchy (SDH) or Multiprotocol Label Switching (MPLS) methods of related bandwidth. However, the latter technologies could be applied to Metro Ethernet in urban areas inclined to dedicate the needed fiscal resources to the activity.
